HARVESTER-BINDER.

SPECIFICATION forming part of Letters Patent No. 242,177, dated May 31, 1881,

' Application filed March 3,1881. (No model.)

citizen of the United States and a resident of- Chicago, in the county of Cook and State of Illinois, have invented'certain new and useful Improvements in Harvester-Binders, of which the following is a specification.

My invention relates to the class of binders represented in Letters Patent of the United States to John F. Appleby, dated February 18, 1879, No. 212,420. In this class of binders, packing arms or fingers are arranged below the chute-board and operate through slots therein to pack or com press the grain into a receptacle preparatory to binding. At the bottom of the receptaclethe grain is partially su pported upon pivoted fingers or bars, against which the grain is pressed by the packers in the formation of the bundle, and when sufiicient grain is so'compressed to form the bundle the force against the fingers causes them to move backward a short distance. In making this backward movement the fingers are arranged to trip and set in motion the machinery which operates the binding-arm and also stop the packers while the bundle is being bound and discharged.

My invention hasreferenceonly to the bar or rod to which the fingers opposite to the packers are pivoted and the manner of connecting this bar or rod with-the binding-arm; and its object is to remedy a defect found to exist in the class of machines referred to.

The accompanying drawings illustrate the invention.

Figurel is alongitudinal section of the chute board, through the slot in which th-ebindingarm operates, showing aside view of the hinding-arm and one of the supporting-fingers in the position which these parts occupy when the packers are in operation. The dotted lines show the backward position of the fingers and the elevation of the trip-lever. Fig. 2 shows the same view as Fig. 1, with the parts shown in the operation of binding and discharging the bundle, the dotted lines showing the position of the fingers when the bundle is being discharged. Fig. 8 is a top or plan view of the parts shownin Figs. 1, 2, without the chuteboard and having the operating-shafts broken away. Fig. 4 is a view of one of the shafts detached.

Like letters of reference refer to like parts throughout the several views.

A designates the chute-hoard; B, the bindin g-arm; C, the supportin g-fingers,which stand in the machine opposite to the packers, which are not shown.

D designates a portion of the supportingframe of the machine.

The chute-board is arranged upon the harvester at an incline of about twenty degrees (more or less) from a horizontal, with its elevated end next to the grain-elevator of the harvester, so thatthe grain as it falls will be caught thereon and will slide down toward the fingers C.

E designates the bar or rod to which the fingers C are pivoted, at 6. This bar is hinged to the arm by an eye, a, on the binding-arm and a pin, 6', fixed on the bar and passing through the eye. The bar is supported in the position shown in Fig. l by a spring, I), acting through shaft b and cranks b I) and pitmanrod 1).

The machinery is tripped by the grain pressing the finger 0 back to the position shown in dotted lines, Fig. 1. In doing this the finger moves on pivot e, elevates the projecting lug a on the bottom of the finger, which raises the tripping-lever a attached to shat't3. The binding-arm is operated by a rockshaft, a.

All of the parts as thus illustrated and described are not materially different from those well known in the class of machines to which reference is made.

In all machines of this class the bar or rod E, which supports the fingers which cause the tripping of the machine, is supported by a spring-support similar to that shown in Fig. 4, and it not unfrequently happens, when the grain is damp or green and from other causes, that the pressure of the grain against the bottom of the fingers C will cause the spring-support to yield before the pressure at the top of the fingers is sufficient to cause their backward movement. The yielding ot' the spring in this manner allows that end of the bar E to which the fingers are pivoted to be borne down and lowered in its position so that the backward movement or" the fingers takingplace after such lowering will not elevate the trip-lever and hence the continuous operation of the packers and clogging of the machine. To avoid this difliculty and remedy the defect, I make the hinge between the binding-arm orits rock-shaft and the finger-support E such as to support this bar in the position shown in Fig". 1 irre' spective of the spring-snpport-that is, the hinge is made entirely rigid at this point, so that it will not allow the other end of the bar to drop any lower, whether it has or has not other support. This rigidity of the hinge at the point desired is best secured by means of a pin or log, 0, upon the bar ll, and a lip or projection, 0, upon the eye 0 arranged to meet at the point desired and prevent any further turning of the hinge. This affords a reliable support to said bar and insures the tripping oi" the mechanism under all circumstances. The pin 0 and projection e do not interfere with each other to prevent the lowering of said bar E to allow the discharge of the bound bundle, owing to the elevated position of the bindingarm, as will be seen at Fig. 2.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In a grain-binder, a support, E, for the compressing and tripping fingers U, hinged to the binding-arm, in combination with a pin, 0, on support E, and a lip, c, on the binding-arm,a1l arranged to operate substantially as and for the purpose specified.
